McNeil Consumer Healthcare, the Johnson & Johnson unit that makes Tylenol, said that the warning is being enforced following research into the misuse of Tylenol by consumers. The new cap message will read: "Contains Acetaminophen" and "Always read the label."

Johnson & Johnson pointed out that warning will appear on the cap of new bottles of Extra Strength Tylenol sold in the US, beginning in October and on most other Tylenol bottles in following months. The warning will make it explicitly clear that the over-the-counter drug contains acetaminophen, a pain-relieving ingredient that is causing sudden liver failure.

Overdoses from acetaminophen send 55,000-to-80,000 people to the emergency room in the US alone each year and kills at least 500, according the Centers for Disease Control and Prevention (CDC) and the US FDA. Acetaminophen can be found in more than 600 common over-the-counter and prescription products used by nearly one in four American adults every week, including household brands like Nyquil cold formula, Excedrin pain tablets and Sudafed sinus pills.
